JOURNAL-Box.

SPECIFICATION forming part of Letters Patent No. 667,470, dated February5,' 1901.

Application filed June 2, 1900.

To all whom, it may concern.-

Beit known that I, FREDERICK G. WARD, a citizen of the UnitedStates,residing at Avalon, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Journal-Box, of which thefollowing is a specification.

The invention relates to improvements in journal-boxes.

One object of the present invention is to improve the construction ofroll-bearing journal-boxes for railway-cars, heavy machinery, and thelike, and to provide a simple and comparatively inexpensive one whichwill be strong and durable and which will be capable of eifectualllyexcluding water and dust and of preventing the antifriction-rolls frombecoming twisted or` grooving the end of the journal-box or thecheck-plate.

A further object of the invention is to provide a journal-box of thischaracter which will afford greater street room or space at the sides ofa car, which will obviate the necessity of notching the footboards orsteps of summer-cars, and which will be ont of the Way of wagons andother vehicles. v

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a vertical longitudinal sectional View of ajournal-box constructed in accordance with this invention. Fig. 2 is atransverse sectional view on line 2 2 of Fig. 1. Fig. 3 is a detailperspective view of one of the spacing-rings. Fig. 4: isa similar viewof the sectional check-plate. Fig. 5 is a detail view of one of therolls.

Like numerals of reference designate corresponding parts in all thefigures of the draw.

ings.

l designates a journal-box provided with a cylindrical bearing-sleeve 2,adapted to be formed integral with or separate from the journal-box andreceiving the journal 3 of an axle e; but the said journal-box may bearranged for the reception of the gudgeon of a shaft or the journal ofany other piece of 'machinery. The journal-box is provided at the bottomwith a recess 6, forming an oil-cellar, which communicates with theinterior of the Serial No. 18,847. (No modelJ upper portion of theoil-cellar, whereby the bearing will be freely supplied with oil whenthe cellar is full.

.annular series of antifriction-rolls 8 is interposed between thejournal and the sleevevt reduce the friction to a minimum. These rolls,which are provided with square-cut ends 9, for a purpose hereinafterdescribed, have annular grooves l0, located near their ends and formingjournals which tit in recesses ll of spacing-rings l2. The recesses ofthe spacing-rings extend inward from the inner surfaces of the same andare rounded to conform to the configuration of the journals land havestraight sides to prevent the rolls from twisting and also to preventany liability or tendency of the journals working inward to the inneredge or periphery of the rings. The straight side walls also prevent thejournals from being broken by being forced beneath the inner edges ofthe rings through any cause whatever. The spacingrings, which aresupported by the journals of the rolls, are of a thickness less than thediameter of the said rolls, so that their inner surfaces and peripheriesare spaced from the journal 3 and from the walls of the sleeve 2 of thejournal-box.

The journal 3 of the axle is extended beyond the rolls and beyond theend of the sleeve and is provided in such extended portion with anannular groove 13, receiving a sectional check-plate 14, adapted to beplaced in position after the rolls have been assemlbled and forming acap for the outer end'ef the roller-case. The sectional check-plateextends beyond the face of the journal 3 and flat or square-cut ends ofthe rolls to arrest the end thrust of the same and prevent the saidrolls from twisting out of position. The fiat or square-cut ends willnot groove the sectional check-plate like tapered or pointed rolls oreven rolls having rounded ends,which are liable to break the check-plateby the end thrust. The sections of the check-plate,which are locatedabove and below the journal of the axle, are secured to the sleeve byscrews 14:, passing through perforations of the sec- The journal of theaxle is of less diameter than the cylindrical bearing-sleeve 2, and anbearing by perforations 7, located below the is adapted to form anabutting face for the IOO tions and engaging suitable threaded socketsof the sleeve.

The sleeve is provided at its inner end with an inwardly-extendingannular flange 15,

against which the flat or square-cut ends of the rolls are adapted toabut, and secured to the inner end of the journal-box in a recessthereof is an annular collar or stufng-box 16, which is provided with arecess 17, forming an annular chamber for a gasket 18. The collar isprovided with a series of perforations for the reception of screws 19,which engage threaded sockets 20 of the inner end of the sleeve, asclearly shown in Fig. 1. The gasket 18 is preferably constructed of hairfelt or other suitable material, hair felt being preferable, as it iselastic and will enable an absolute dust-proof joint or connection to beprovidedl Without creating friction. The collar or stuffing-box isadapted to be adjusted by the screws 19 to compress the gasket and causethe same to conform closely to the j ournal of the axle.

The outer end of the sleeve may be closed by a cap 21, having a recess23 for the reception of the outer end of the journal 3 of the axle. Thecap-plate is provided near its periphery with perforations for thereception of screws 25, which engage suitable threaded sockets 26 of thesections of the check-plate to which the cap 21 is secured, thecheck-plate being interposed between the outer end of the sleeve and thecap. The cap conceals the outer end of the journal 3, which projectsbeyond the sleeve, and it is adapted to dispense with the ordinaryhinged lid when it is desired to construct journal-boxes for streetcars,and by omitting the hinged lid or cover (shown in Fig. l) and employingonly the bearing portion of the journalbox the streetspace at the sidesof the car will be increased and the journal-boxes will be arranged ontof the Way of vehicles and the notching of the steps or running-boardsof summer-cars will be obviated.

Instead of constructing the journal-box as just described, which issubstantially the interior construction illustrated in Figs. 1 and 2,the journal-box may be shaped to conform j softe the configuration ofthe ordinary form of journal-boxes in use on railway-car trucks,

. and it may be provided with a hinged lid or cover 27, and it may haveupper recesses 5 and have an integral cylindrical bearing portionforming the sleeve 2 and constituting the case for the rolls, and Idesire it to be understood that these and similar changes may beresorted to without departing from the spirit or sacrificing any of theadvantages of the invention.

It will be seen that the journal-box is simple and comparativelyinexpensive in construction, that it reduces the friction to a minimum,and that the square-cut or flat ends of the antifriction-rolls willprevent the latter from catching on the sectional ring or the flange atthe inner end of the journal-box. It will also be apparent that theflat-ended rolls will not be displaced by an end thrust of the axle andwill not cut or groove the adjacent abutting surfaces like tapered,rounded, or pointed rolls and that the journal-box is capable ofeffectually excluding both dust and Water. Furthermore, it will be clearthat the antifriction-rolls have a free and independent movement and areadapted to adjust themselves to the upper side of the journal of theaxle and that the spacing-rings are held out of contact with the axleand the journal-box. The sectional ring, which is interlocked with theaxle, prevents the rolls from coming in contact with the cap orcheck-plate and avoids the tendency to longitudinal play, which willnecessarily result when there is a space at either end of the rolls.

What I claim is- 1. In a device of the class described, the combinationof a journal-box having a sleeve provided at its inner end with a ange,a journal 3 having an extended portion provided With a groove, asectional check-plate interlocked with the groove and arranged at theouter end of the sleeve, a cap secured to and concealing the check-plateand the extended end of the journal, the flat-ended rolls arrangedwithin the sleeve and provided between their ends With grooves, andspacingrings engaging the grooved portions of the rolls, substantiallyas described.

2. In a device of the class described, the combination of a journal-boxhaving a sleeve provided at its inner end with a flange, saidjournal-box being also provided with a recess, a journal having anextended portion provided with a groove, a check-plate composed ofsections secured to the outer end of the sleeve and interlocked with thegroove of the journal, a cap also secured to the outer end of the sleeveand concealing the journal and the check-plate, antifriction-rollsarranged within the sleeve, bearing or spacing rings-arranged on therolls in grooves thereof, a collar secured in the recess of thejournal-box at the inner end thereof, and provided with a recess 17, anda gasket arranged within the recess 17 and adapted to exclude dust andwater, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
